When I suggested to Jim to call real virFileExists() I forgot to also suggest calling init_syms(). Without it, real_virFileExists pointer might be left unset. And indeed, that's what we were seeing on FreeBSD.

Thanks for fixing the mess from my small patch :-). I was deep in another task when I noticed the build failure, but that's a poor excuse for not properly investigating it and pushing a hurried fix. Reviewed-by: Jim Fehlig <jfehlig@suse.com> Regards, Jim

Okay, it doesn't test FreeBSD, but it tests x86_64-ubuntu-2204-clang which was also experiencing the failure:
